Abstract
The invention provides a yarn dyeing process dispensing with pretreatment. The process comprises the following steps: slack winding or warping, dyeing and post-treatment. The method is characterized by adopting a one bath process to firstly permeate the yarns in an LTWB auxiliary and then color the yarns in the dyeing procedure, wherein the LTWB auxiliary is formed by alkyl metaphosphate ester and polyethylene glycol ester in a weight ratio of (20-35):(65-80). The process has the following advantages: the yarns are firstly permeated in the LTWB auxiliary, thus shortening the dyeing process time and reducing the discharge times of the dye bath; the fabrics have natural softness and smoothness; the waxy substances in the cellulose fibers are not removed in the whole process; the cellulose fibers can be swollen; the pH value in the dye bath is moderate; and the dye can dye the fibers to the greatest extent to achieve the effect of uniformity.
Description
Technical field
The present invention relates to a kind of yarn dyeing technology of exempting from pre-treatment, belong to textile technology field.
Technical background
Cotton goods are exactly the fabrics that people heat is held in both hands since ancient times, and it has softness, warming, endurable, good moisture absorbing and sweat releasing effect, is also generally acknowledged it is good textiles by everybody on cotton planting, staining technique always.Cotton fiber is easy to dyeing, and it is mainly reflected on the performance of fiber itself, can make dyestuff reach good dye-uptake and has good COLOR FASTNESS, and this also is that other fabric is inaccessiable.Though but just accounted for 6% of total amount for the impurity in the cotton fiber, but in dyeing course, still Color is had very big influence, it both had influence on dyestuff on dye, cause very big a part of dye loss, also have influence on tube yarn inherent quality, caused raw-material waste.No matter traditional pre-treatment process is bleaching process or enzyme boiling, all is at the impurity of removing in the cotton fiber, causes the dyeing time long, sewage discharge often, energy consumption is many, the kind of adding auxiliary agent is many, and sewage disposal has also been increased some difficulties.
Summary of the invention
Purpose of the present invention just provides the yarn dyeing technology of exempting from pre-treatment of soft yarns function admirable after a kind of defective that can overcome above-mentioned technological process, energy-saving and emission-reduction, the processing.Its technical scheme is:
May further comprise the steps: loose type coning or warping, dyeing and post processing, it is characterized in that: dyeing process adopts one to bathe, yarn is carried out the infiltration of LTWB auxiliary agent earlier, and then paint, wherein the LTWB auxiliary agent is made up of alkyl metaphosphate and Macrogol Ester, and both mass percents are 20～35: 65～80.
Described yarn dyeing technology of exempting from pre-treatment, at loose type coning or warping process, loose formula tube yarn density scope is 0.32～0.35g/cm
3, warping is 0.40～0.45g/cm through the axle density range
3
Described yarn dyeing technology of exempting from pre-treatment, in dyeing process, at first carry out LTWB auxiliary agent infiltration: with LTWB auxiliary agent and water with 1～3: 500 mass ratio mixes the formation penetrating fluid, and yarn is immersed in the penetrating fluid, treatment temperature: 50 ℃～60 ℃, the time: 40 minutes ± 1 minute; Colouring then, circulation adding glauber salt in the penetrating fluid, consumption 10～80g/L, add dyestuff again, use anhydrous soda ash during colouring process fixation, add in the mode of ratio dosing, consumption flows to and adopts interior stream circulation 2 minutes, outflow circulation 3 minutes at 10～20g/L, hockets, pump speed is transferred to 95%, flow velocity is 40L/ minute * kilogram yarn, 90 ℃ ± 1 ℃ of dyeing temperature, 60 minutes time, do not need to add retarding agents and levelling agent, discharging after dyeing is finished.
Described yarn dyeing technology of exempting from pre-treatment, in postprocessing working procedures, the tube yarn does not carry out oiling process.
The present invention compared with prior art, its advantage is:
1, saved pretreatment procedure, saved oiling process in the postprocessing working procedures, the infiltration of LTWB auxiliary agent finishes the back penetrating fluid and does not discharge, directly carry out next step colouring, when colouring, do not need to add retarding agents or levelling agent, the LTWB auxiliary agent just can help dyestuff to dye on the yarn on directly, and plays the purpose of level dyeing.
2, make full use of the hydroxyl on the yarn fibers cellulose fiber and the reactive group generation bonding reaction of dyestuff.After adding the LTWB auxiliary agent, the cell passage of yarn fibers cellulose fiber is opened gradually, make the hydroxyl on the yarn fibers cellulose fiber have more very big activity space, can fully touch the reactive group of dyestuff, dye molecule reaches by the effect of LTWB auxiliary agent and dyes and even dyeing effect on maximum.Simultaneously, along with the diastole meeting of yarn fibers cellulose fiber loses tractive force to impurity cotton seed hulls etc. gradually, impurity such as cotton seed hulls can be flushed away along with the discharging of dye liquor in later process.And the pH value of dye bath remains under the neutrality or the condition of weak base, makes that the wax in the yarn fibers cellulose fiber remains, and no longer needs to add oil agent when in the end dyeing finishes.
3, because saved pretreatment procedure,, reduced sewage emissions so shortened the dyeing time; Save auxiliary agent used in the pretreatment procedure, the pH value of yarn is reduced, had more softness, endurable effect.
4, in the postprocessing working procedures because a tube yarn does not carry out oiling process, more environmental protection, and the wax in the yarn fibers cellulose fiber is present in fibrous inside and the cell, is in the suds to be difficult to remove, soft feel is more lasting.
